"Missing ACK" Error with AMG8833 & H7 Plus

OpenMV Products

Hi all!
I used successfully an OpenMV3 together with a AMG8833 thermopile sensor. Now I graded up to a OpenMV H7 PLUS with GLOBAL SHUTTER CAM module. A i2c.scan shows, that the AMG8833 ist recognized, but the fir.init routine gives me an “Missing ACK” back. Did I make a mistake or is there just a problem with compatibility?

Cheers,
Thomas

Does I2C scan find it or not?

I will have to test.

Hi, I’ve found a bug in the software I2C on the H7, I’ll fix it and this fix will be in the next release (which will be out in a few days.)
